Review on 📺 J-Tech Digital ProAV HDMI Extender: Crystal Clear 1080p Over Single Cat5e/6 Cable up to 400' with IR Extension [TX + RX] by Nick Kirschenmann

I really liked these devices. We streamed with an HDMI projector at the front of the room and a second (VGA) projector halfway back. The transmitter was connected to the same HDMI hub that the front projector was connected to. After more than 50 meters to the receiver, the signal for the old projector had to be converted from HDMI to VGA in the background. Both screens were viewable from the rear projector and there was absolutely no noticeable lag between them. This was important as the transmission was mostly through the speakers and the delay would be very noticeable if the words didn't match the lips. We were a little concerned about this, as devices obviously need to encapsulate video data in IP packets on transmission and extract data from IP packets on reception. Both can cause delays. We know they do this because they can transmit over standard UK network switches. Good job folks!
